Manage SMS Route

Decide which destination countries your account is allowed to send to. Block the countries you never message — it prevents accidental international sends and keeps your spend predictable.

How routing works

Open User Profile → Manage SMS Route. Every country has a route that’s either Active (your SMS can go there) or Blocked (sends are stopped). The summary shows your totals at a glance.

Block or unblock a country

  1. 1

    Find the country

    Use the A–Z letter filter to jump to a country. Each row shows its dialling prefix and current status.

  2. 2

    Block a single route

    Click Block next to an active country to stop SMS to it. Blocked countries show a red Blocked badge.

  3. 3

    Block several at once

    Tick the countries you want (or use Select All), then click Block Selected. Use Deselect All to clear your selection.

The iSMS Manage SMS Route screen: totals for active and blocked routes, an A-Z filter, and a country list with prefix, status, and Block actions.

Blocking stops all SMS to that country until you re-enable it. If a campaign suddenly shows undelivered messages to one country, check whether its route is blocked here.
